How long can I use a large-sized moisturizing cream after opening it?

I like large quantities of everything.

Maybe it's because I'm lazy, but I prefer buying something, forgetting about it, and just using it continuously.

However, one of the concerns regarding large-sized moisturizing creams is the expiration date.

The expiration date is literally the period during which a product can be distributed unopened, so it is different from the use-by date.

Usually, how long can a large-sized moisturizing cream be used after opening?

I don't think a whole year will be that long, so I try to use it up as soon as possible, but sometimes the period ends up dragging on.

I would appreciate it if you could share some tips on how to use a large-sized moisturizer for a long time after opening, or recommend any products that have a relatively long shelf life.
